  • the uniformity of the lining density and the mold release characteristics become problems. Since the surface on which the lining is pressure-bonded is a peripheral surface, the raw material of the lining cannot be uniformly compressed from near the center to near the end. In particular, the lining edge cannot be pressed sufficiently because the molding surface and the pressing direction are not perpendicular to each other, and it is difficult to make the density of the edges uniform.

  • the drum brake is premised on generating a braking force by pressing a lining, which is a friction material, on the inner peripheral surface of the drum, the brake lining is formed to have a circumferential friction surface. Therefore, when the lining material is pressed against the outer peripheral surface of the rim and the lining is pressure-bonded, there are not only portions where the forming surface for forming the friction surface of the lining and the compression direction are orthogonal to each other, but also portions that cross obliquely. When the molding surface for forming the friction surface is orthogonal to the compression direction, the compression force is efficiently transmitted to the raw material, and the raw material is reliably compression-molded. This is because the compression force does not diffuse in a direction different from the compression direction.
  • the compression force is not efficiently transmitted to the raw material compared to the case where the forming surface is orthogonal.
  • the compression force transmitted to the raw material gradually decreases as the molding surface and the compression direction become closer to parallel.
